Cooling Fluid Opening Surface Analysis for Precise Reopening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processes for reopening cooling fluid openings on components, such as turbine blades, after coating are inefficient and prone to errors due to deviations in position and orientation caused by manufacturing tolerances and geometry changes, leading to inaccurate and time-consuming measurement methods that are not reliable for precise industrial applications.
Innovation Solution
A two-part surface analysis process using an apparatus with measuring devices and fastening systems that determine the position and three-dimensional shape of cooling fluid openings, allowing for automated and precise reopening of these openings, even without reliable construction data, by using movable elements and different measurement methods for high accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional measurement methods are used to determine cooling fluid opening positions after coating, then the process can be completed, but the measurement is too time-consuming and inflexible for real industrial processes
Solution Approach 1:
The patent applies preliminary action by performing surface analysis measurements before the coating process to capture the original positions and geometries of cooling fluid openings. This preliminary data is stored and later used to guide the reopening process, eliminating the need for time-consuming post-coating measurements and enabling rapid maintenance operations.
2Ease of manufacture
If construction data is used to determine cooling fluid opening positions, then the process is simplified, but deviations occur due to manufacturing tolerances and geometry changes during operation
Solution Approach 1:
The patent implements feedback by capturing actual surface measurements of the component before coating, storing this real data, and using it to guide the reopening process. This feedback loop ensures that the actual positions and geometries (which may differ from construction data due to tolerances or deformation) are used, achieving both ease of process and high precision.
3Ease of operation
If manual methods are used to remove coating from cooling fluid openings, then flexibility is maintained, but human error increases and reliability decreases
Solution Approach 1:
The patent replaces manual mechanical methods with an automated system that uses surface analysis data to control a laser or other removal device. The measured positions and geometries of cooling fluid openings are used to automatically guide the coating removal process, eliminating human error while maintaining the flexibility to adapt to actual component variations.
4Device complexity
If existing surface analysis apparatuses are used, then basic measurement capability is provided, but they give too little or too inaccurate information for precise reopening
Solution Approach 1:
The patent enhances basic surface analysis by capturing three-dimensional geometric information in addition to two-dimensional position data. This multi-dimensional measurement approach provides comprehensive information about the cooling fluid openings including their shapes, orientations, and depths, enabling precise reopening while using relatively simple measurement apparatus.
